Famous quotes containing the words applied and/or chemistry:

“A propositional sign, applied and thought out, is a thought. A thought is a proposition with a sense.”
—Ludwig Wittgenstein (1889–1951)

“...some sort of false logic has crept into our schools, for the people whom I have seen doing housework or cooking know nothing of botany or chemistry, and the people who know botany and chemistry do not cook or sweep. The conclusion seems to be, if one knows chemistry she must not cook or do housework.”
